A Celtic fan is walking home from a match in his Celtic kit. He fancies a drink, walks into a bar and found himself surrounded by blue and white. He's walked into a Rangers' bar. A deadly silence falls over the pub. Then the barman clears his throat and says, "In here, we give Celtic fans a toll of the dice. "If you roll one to five, we kill you."
The Celtic fan replies,"What happens if I roll a six?"
"You get to roll again."
